Answer:
Hence After 2 years from 2009 to 2011 THe price for share of stock will be 5.8141 $
Step-by-step explanation:
Given:
Initial price=$5.36
Rate=4.15 %
To Find:
Function which represents the growth price for stock market?
Solution:
As the function is growing one and with same rate and depends upon the time period ,
So the exponential function as
[tex]P=A(1+R)^t[/tex] will the required function ,
So P will be price of stock at t time period with R as rate for function.
A be the previous year price
From 2009 to 2013 rate is 4.15 %
we have to find price after 2 years
So t=2 , A at 2009 =5.36$
So P at 2011 will be given by,
[tex]P=A(1+R)^t[/tex]
[tex]P=5.36(1+0.0415)^2[/tex]
[tex]P=5.36(1.0415)^2[/tex]
[tex]P=5.8141 $[/tex]
Which linear function represents the table? A) y = 7x − 7 B) y = 7x + 7 C) y = −7x + 7 D) y = −7x − 7
Answer:
Y = -7x+7
Step-by-step explanation:
(This takes a while)
A) Y = 7x - 7
B) Y = 7x + 7
C) Y = -7x + 7
D) Y = - 7x - 7
The asnwer is: C.
Because by distribution the numbers of [x], you will find that you will get [y]. And when you must do this with each of them in order to find out which is the right function.
(6,-35) -> Subsitute 6 into [x]:
Y = 7(6) - 7
Y = 42 - 7
Y = 35
This is wrong, because [y] is supposed to equal -35 and not 35. So A. is out.
B. is also positive, so that means you can't get a negative from it either, so that's out.
C. and D. are both negative, so its between these two.
Y = -7x + 7
Y = -7(6) +7
Y = -42 +7
Y = -35 <- Okay, so that's correct, now let's check D.
Y = -7(6) - 7
Y = -42 - 7
Y = -49 <- This answer is wrong, so your correct answer is C!
The best thing to do is distribute into each, it's quite a process, but it'll help you find out the answer!
Which equation has x = 4 as the solution?
olog,(3x+4)= 2
log, (2x-5) = 2
log, 64=4
log, 16 =4
The equation that has the solution x = 4 is [tex]log_ 4 (3x+4) = 2[/tex].
Option A is the correct answer.
What is a solution?Solutions are the values of an equation where the values are substituted in the variables of the equation and make the equality in the equation true.
We also find the solution in a system of equations using the substitution or elimination method.
Example:
2x + 4 = 8
The solution is x = 2.
We have,
To find which equation has x = 4 as the solution,
We can substitute x = 4 into each equation and see which one gives a true statement.
Now,
[tex]log_4 (3x+4) = 2\\log_3 (2x-5) = 2\\log_x 64 = 4\\log_x 16 = 4[/tex]
We can write it as,
4² = 3x + 4
16 = 3x + 4
16 - 4 = 3x
3x = 12
x = 4
3² = 2x - 5
9 = 2x - 5
9 + 5 = 2x
14 = 2x
x = 7
[tex]x^4[/tex] = 64
x = [tex]64^{1/4}[/tex]
[tex]x^4[/tex] = 16
x = 16[tex]16^{1/4}[/tex]
x = 2
Thus,

The volume of the cylinder above is 2314.25units3 , and the radius of the base is 8.9 units. Find the volume of the cone.
Answer:
771.4 units^3
Step-by-step explanation:
Formula for volume of a cylinder = V=πr^2h
Plug in the numbers to solve for the height (note: the height of an oblique or slanted cylinder is the same as a regular right cylinder)
2314.25 = π(8.9)^2 h
h=9.3
Then plug the height into the formula for a pyramid
V = 1/3πr^2
V = 1/3 π (8.9)^2 (9.3)
V = 771.4 units ^3

(EASY) How much does the music store charge for a yearly membership?
The music store will charge $5 for a yearly membership.
Step-by-step explanation:
Let the cost per vinyl album be 'a'
Let the yearly membership cost be 'b'
Given that,
4a + b = 35
7a + b = 57.5
9a + b = 72.5
We can take any 2 equations from the above,
(4a + b = 35 ) - (7a +b =57.5)
4a + b - 7a - b = 35 - 57.5
-3a = -22. 5
3a = 22.5
a = 7.5
The cost of each vinyl album is $7.5
4a + b = 35
4(7.5) + b = 35
30 + b = 35
b = 35 - 30
b = 5
The cost of the yearly membership is $5
The music store will charge $5 for a yearly membership.

Answer:
the answer is the expression, 5n-3
Step-by-step explanation:
Answer:
The value of n is -3/2.
Step-by-step explanation:
In order to solve x, you have to use the Cross-Multiplication :
[tex] \frac{ - 3}{5n} = \frac{2}{5} [/tex]
[tex] - 3(5) = 2(5n)[/tex]
[tex] - 15 = 10n[/tex]
[tex]10n \div 10 = - 15 \div 10[/tex]
[tex]n = \frac{ - 15}{10} [/tex]

You can find that because on the graph, the top of the curve is on Y and its positive. Its at positive 4 so its positive......sorry im not good at explaning hope this helped.....also you can check google images or videos and it explanes.
Answer:
Positive
Step-by-step explanation:
In order to answer this question, we need to figure out the equation of the quadratic.
We see that the vertex is at (0, 4) and that the points (1, 3) and (2, 0) are on the graph. The generic quadratic is: ax^2 + bx + c, so we can just plug in these three points to find a, b, and c:
4 = 0 + 0 + c ⇒ c = 4
3 = a + b + c = a + b + 4 ⇒ a + b = -1
0 = 4a + 2b + c = 4a + 2b + 4 ⇒ 4a + 2b = -4
We now have two linear equations (a + b = -1 and 4a + 2b = -4) so multiply the first one by 2 and subtract it from the second:
4a + 2b = -4 ⇒ 4a + 2b = -4
- 2(a + b) = (-1) * 2 ⇒ - 2a + 2b = -2
______________ ⇒ ______________
Our difference is 2a = -2, so a = -1. Plug this back in to find b: a + b = -1.
-1 + b = -1
b = 0
So our equation is -x^2 + 4 = 0.
The discriminant is just b^2 - 4ac. Here, it is: 0^2 - 4 * (-1) * (4) = 16.
So the discriminant is positive.
Hope this helps!

a plane averaged 400 mph on a trip going east, but only 280 mph on the return trip. The total flying time in both directions was 8.5 hours. what was the one-way distance?
Answer:
1400 miles
Step-by-step explanation:
Speed is the time rate of change of distance. It is the ratio of distance to time and is given by the equation:
[tex]Speed(S) = \frac{distance(d)}{time(t)}\\ S=\frac{d}{t}[/tex]
plane averaged 400 mph on a trip going east, but only 280 mph on the return trip.
The time spent (t₁) in going east is given by:
[tex]S=\frac{d}{t_1}\\ t_1=\frac{d}{S} =\frac{d}{400mph}[/tex]
The time spent (t₂) in going east is given by:
[tex]S=\frac{d}{t_2}\\ t_2=\frac{d}{S} =\frac{d}{280mph}[/tex]
The total time (t) = t₁ + t₂
t = t₁ + t₂ = 8.5 hours
[tex]\frac{d}{400}+\frac{d}{280} =8.5\\280d+400d=952000\\680d=952000\\d=1400miles\\[/tex]
Therefore the one way distance is 1400 miles

{(1217,5/7)
{(16/7.9/7)]
(5/7, 12/7) <- I think you meant to type that. Its the first one
Step-by-step explanation:Step 1: Substitute y=x+1 in for y in 5x + 2y = 7
5x + 2(x+1) = 7
Step 2: Solve it
5x + 2x + 2 = 7
7x + 2 = 7
- 2 - 2
7x = 5
--- ---
7 7
x = 5/7
Step 3; Plug x into y=x+1
y = 5/7 + 1
y = 12/7
Answer:
{(5/7 , 12/7)}
Step-by-step explanation:
First plug y into one of the x's
5x + 2(x + 1) = 7
Now solve for X
5x + 2x + 2 = 7
Combine like terms
7x + 2 = 7
Subtract 2 from each side
7x = 5
Divide to get x by itself
x = 5/7
Now plug that into the second equation for x
y = 5/7 + 1
now just solve it
y = 12/7 if they want it simplified then it's 1 5/7
Hope this helped!

how do you solve this
Answer:
x=-26
Step-by-step explanation:
Distributive property first (both sides)
you would get
4x+2 = 3x-24
next you will subtract 3x from both sides
1x+2=-24
add 24 to both sides
1x+26=0
move 26 to the other side but since you flipped it you have to make it negative
x=-26
Khloe ran around the track 7 times at the same rate of speed. It took her 21 minutes to run. Zachary took 4 minutes to run around the track once. Which student ran faster? Explain.
Zachary ran faster with 4 minutes per lap compared to Khloe's 3 minutes per lap.
To compare the speeds of Khloe and Zachary, we need to find their respective speeds in terms of minutes per lap.
Khloe ran around the track 7 times in 21 minutes, so her speed is [tex]\( \frac{21}{7} = 3 \)[/tex] minutes per lap.
Zachary took 4 minutes to run around the track once, so his speed is [tex]\( 4 \)[/tex] minutes per lap.
Comparing their speeds, Zachary's speed is faster at 4 minutes per lap, whereas Khloe's speed is 3 minutes per lap.
In summary, Zachary ran faster than Khloe because he completed each lap in 4 minutes compared to Khloe's 3 minutes per lap.

x = 0.3636...... equ(ii) {Now, subtract equ (ii) form (i)
99x = 36
x = 36/99
x = 4/11
0.3636...... = 4/11
B) __
0.36 = 0.366666.....
{After decimal point two digits are there but only one digit, 6 is repeated. so first multiply both sides of equation [x=0.366...] by 100 and mark it as equation (i) and then multiply both sides of the equation [x=0.366...] by 10 and mark it as (ii) equation }
x = 0.3666....
100x = 36.66666..... ---------- (i)
10x = 3.66666...... ---------(ii) {Now subtract (ii) from (i)}
90x = 33
x = 33/90
x = 11/30
0.36666..... = 11/30
